All the angles of triangle add up to 180 degrees.
so 42+63+x=180
add 42 and 63 then subtract that from 180.
42+63= 105
180-105= 75
so it's 75 degrees.

75 degrees because 42+63=105
180-105=x

What are significant figures?

scZoUnD [109]

Answer:

Significant Figures are the figures in a number that are meaningful and are digits with no zeros. Those zeros can be traced in a number like “320”, or “5670.0045”. Those zeros are not counted when counting the significant figures.

I hope you understand.

Justin has $7.50 more then Eva, and Emma has $12 less than Justin. Together, they have a total of $63.00. How much money does ea

PilotLPTM [1.2K]

To make it easier, lets say Justin = J, Eva = E, and Emma = M. Then, J = E + 7.50 M = J -12 J + E + M = 63 You can substitute for M in the third equation using the second equation, and you get: J + E + J - 12 = 63 Clean it up a little bit and you get: 2J + E = 75 You know J = E + 7.50, so substitute that for J and you get: 2(E + 7.50) + E = 75 2E + 15 + E = 75 3E + 15 = 75 3E = 60 E = 20 ; meaning that Eva has $20. Justin has $7.50 more than Eva, so he has $27.50. Emma has $12 less than Justin, so Emma has $15.50. Double check your answer by making sure they all add up to 63, which they do.
